PHP Form Handling

PHP Form Handling

The PHP superglobals $_GET and $_POST are used to collect form-data.

GET vs POST

  • GET: Appends form-data into the URL. Never use GET to send sensitive data. Max URL length is 2048 characters. Useful for bookmarking.
  • POST: Appends form-data inside the body of the HTTP request (not shown in the URL). Has no size limitation. Secure for sensitive data like passwords.
